New maturity cycle charts for the herring stocks along the west coast of Newfoundland (NAFO division 4R) and the north shore of Quebec (NAFO division 4S) / by I.H. McQuinn.: Fs70-8/87-66E-PDF

"A study was conducted to describe the annual evolution of the gonadal development of west coast of Newfoundland and Quebec north shore herring in order to add precision to the maturity cycle chart used to separate the spring and autumn spawners in these stocks. A separate maturity cycle chart was produced for both males and females in NAFO Divisions 4R and 4S which classified individual fish as a spring or autumn spawner from its maturity stage, calculated from the gonadosomatic index, and the month of capture. The results showed the annual maturity cycles of these stocks differed substantially from the chart presently used by CAFSAC. The new maturity cycle charts should enable more accurate spawning type determinations from the historical as well as from future sampling data"--Abstract, page i.
